LOCK;

SPECIFICATION forming 1.2m of Letters vPatent No. 647,430, dated April' 1go, 1900; Applicants tied Dtente 23,1899. sei-u1 No. 741.454. (Nomoib pertains to make and use the same, reference being had to the accompanying-drawings, and to the letters of reference marked thereon, which form a part of this specification.

The objects of this invention are to secure a hasp=lock which will lock automatically by simply pressing the hinged hasp into the cooperating keeper, to provide such a lock in `which the parts are after unlocking automatically returned into position for `locking and the lock thus always ready to be automatically locked, to enable this automatic action to take place whether the key is removed or not and to enable said key to be as well removed after locking as before, to enable either a fiat key or a barrel-key to be used for opening the lock, to provide a cheap and sim ple construction, and to secure other advantages and results, some of which may be referred to hereinafter in connection with the description of the working parts.

The invention consists in the improved hasp-lock for trunks and in the arrangements and. combinations ofv parts of the same, allsubstantially as will be hereinafter set forth and finally embraced inthe clauses of the claim.

Referring to the accompanying drawings,

in which like letters of reference indicate corresponding parts in each of the several views, Figure l is a front view of the hasp-lock and keeper applied to a trunk and showing the same in opened position. Fig. 2 is a section of the same on line :0, Fig. 1. Fig. 3 is a sectional view of vthe'keeper, taken on line Fig. 1. Fig. 4 is a front view of a modied form of keeper sometimes preferred; and Fig. is a section of the same on line y, Fig. 4. Fig. 6 is a rear View of the lock closed and showing the T-headed bolt in locked relation to the keeper. Fig. 7 is a plan of the lock proper detached from the hasp. Fig. 8 is a similar plan of the lock with the top plate removed and showing the parts in their unlocked position; and Fig. 9 is a plan showing the top plate, tumblers, and middle plate removed. Fig. 10 is a central cross-section of the lock on line e, Fig. 7. Fig. l1 is an edge view of the lock,'showing the engaging position of a certain tumbler-detent in the unlocked lock; and Fig. 12 is a similar view of the same in its disengaging position when the lock is locked. Fig. 13 is a plan of the lock with its parts in locked position and the top plate removed. Figs. 14 and lef;L show in perspective the tumblers preferably employed. Fig. 15 is a spring for said tumblers. Fig. 16 is a view of one of the partition-plates. Figs. 17 and 1S are front and rear views, respectively, of the rotary bolt-carrier. Fig. 19 is a side View of a key which may be employed, and Figs. 20 and 21 show a modified form of tumbler-detent sometimes preferred.

In said drawings, d indicates the body of a trunk or the like, to which is attached the hinged hasp b, and a indicates the cover of thetrunk and having thereupon the keeper c. Said hasp carries at its endy in the usual position a lock b', adapted to beseated in the recess o of the keeper and having a Theaded bolt d, adapted to pass through a slot or aperture CZ' in the bottom of the keeper and be turned to lie across said slot, at the back thereof, as shown in Fig. 6. The said keeper is one int-egral piece fixed upon the trunk-cover,

and theT-headed bolt when the hasp and keeper are not pressed together into locked engagement oscillates against the power of a spring which normally holds said T-head in its transverse locking position with reference to the keeper-slot, as will be hereinafter more fully described. The lugs d2 of the T-headed bolt are preferably beveled at the side, whereby as they strike the edges of the slot in the keeper when the parts are pressed together said bolt is rotated backwardlyagainst the power of its spring to allow it to enter the slot. I may sometimes prefer to also bevel the edges of the slot to Vfurther facilitate the entrance of the bolt., or under some conditions the edges of the slot may be beveled and not the lugs of the bolt-head.

Referring now to the interior lock mechanism, which is inclosed in the case e, riveted .by the {iange e' to the hasp, as is usual, f is IOO a stationary top plate which serves to partially cover the parts beneath and may be used or not, as desired.

g' and g indicate fixed posts projecting up- Ward from the bottom of the lock-case e.

H and h are tumblers pivoted on the post g and actuated by a spring i, andj is a stationary middle plate separating the said tumblers from the movable parts beneath. Below said middle plate j is the oscillating boltcarrier k, shown in the drawings as composed of a lower portion 7c', having an upper plate 7a2 riveted thereupon. Obviously these two parts could be cast in one piece, if preferred. Said bolt-plate rests at its lower side upon the bottom of the lock-casing and has a reduced stem k3 projecting through an aperture in the bottom of the casing and being suitably shaped to receive at its extremity the T-head d.

The bolt-carrier 7a is cent-rally recessed at .the top to receive the lower end of a rotary key-guide Z, which is commonly used in connection with fiat keys and which bears at its opposite end in the keyhole in the hasp. If a barrel-key is preferred, the said carrier 7c has instead of the recess an upwardly-projecting pin to receive the key, all as is common in the art.

The upper plate 7a of the bolt-carrier projects peripherally over the lower portion 7a2, to which it is riveted, and is segmentally recessed to form stops m m', adapted to engage the studs g g and limit oscillation of the boltcarrier'and bolt. A spring is also provided to normally hold the stop m in contact with thepost g, which secures such a position of the bolt-carrier kthat the T-headed bolt lies in' its transverse or locked position.' This spring maybe arranged in any manner capable of effecting the result described; butI prefer to use a coiled wire n, lying near the walls of the casing e and around the bolt-,carrier 7o and being secured at one end to the periphery of the plate 7c', as at n', and at the other end to the casing e, as at n2. The mid- `dle of the plate 7c' is open, and a segmental projection 0 extends toward the center and provides a shoulder o', against which the key may impinge to oscillate the bolt-carrier and bolt against the spring nin unlocking. This reversed oscillation by the keycontinues until the stop m engages the post g', when the T-headed bolt may be withdrawn from the keeper-slot. The key is also in this position in alinement with the keyhole-slot and may be withdrawn, when the spring n Will instantly return the bolt-carrier to its initial position. The key, however, is not necessarily withdrawn, for if only the pressure of the fingers upon the key is relaxed said key will be carried backward with the bolt-carrier under the power of the spring n. The key can then be freely removed at any time by turning it in a reversed direction until itengages the shoulder 02 of the stop o before described.

To secure a locking of the bolt-carrier against oscillation when the T-headed boltis in locked engagement with the keeper, I employ one or more tumblers common in the art. These tumblers have a slot 7L' with a recess h2 at the closed end of said slot, and a stud p upon the bolt-carrier works in said slot. When the lock is in locked condition, the tumblers are thrown and held in an inward position by the spring or springs t', as shown in Fig. 13, thus catching the stud p in the recess h2 and preventing oscillation of the bolt-carrier. When the lock is opened, however, by the key, said tumblers are pushed back against the wall of the casing e, so that the stud p can pass through the slot h'. It is obvious that in my invention this locking of the bolt against oscillatory movement must occur only when the T-headed bolt is in locked engagement with the keeper and not when said bolt is merely in locking position, for this is its normal position atall times, and it must oscillate therefrom as it engages the keeper in automatically'locking. To accomplish this feature of my invention, I prefer to use the means next described.

Upon the lock-casing e. I pivot a detent-lever having at one end a tooth extending through the casin g to engage the extremities of the tumblers. A spring normally holds said lever in engagement with the tumblers, and the end of the lever opposite the tooth is adapted to be engaged by the keeper as the lock isseated therein and move the said lever against the power of its spring and release the tumblers.

The preferred form of detent-lever q is pivoted upon the outer wall of the casing c by means of a pin q', so that it swings in a direction at right angles to the plane of the lock-case, the lever being suitably curved to lie adjacent to the case. One end of the lever is bent inward, as at q2, through a slot e? in the casing, and this tooth catches the eX- tremities of the tumblers, as shown in Fig. 8, as long as this toothed end of the lever is in elevated position, where it is normally held by a spring r. The opposite end of the lever is beveled, as at s, and when the lockis pressed into the keeper this beveled end of the lever engages a correspondingly-beveled seat s and turns the lever against the power of the spring r, releasing the tooth q from the tumblers and permitting them to act. In unlocking the lever q at once regains its normal position as the hasp is opened from the keeper and the tooth catches the tumblers which have been pushed back by the key. Under some conditions I may pivot the lever upon the lock-case iiange, as shown in Figs. 20 and 21 and marked Q, in which case it swings in the plane of the lock and the tooth moves in and out of the slot. For this form of lever a bearingv,slanting radially inward, must be formed on the keeper, as shown in Figs. 4 and 5. In

`both cases the lever lies in a recess u, formed in the walls of the keeper.

Sometimes in using the trunk in an unlocked condition it may be desired to prevent any possible inadvertent pressure of the lockbolt into its keeper, such as would lock the trunk and necessitate a use of the key in again unlocking. Under these circumstances it Will be obvious that a pressure of the iinger upon the exposed detent will serve to release thev tumblers, and thus lock the bolt against oscillation, so that it cannot enter the keeper. The original state of things can at any time be restored by use of the key, so that a locking of the trunk may be effected. Having thus described the invention, what I claim as new isl. In a lock, the combination of a keeper, an oscillating lock-bolt, a spring normally holding said lock-bolt in. locked position but said tumblers adapted to be released by pressure of the lock-bolt into the keeper, substantially as set forth. i
